Shalnov [3]

So you just want to find out how many groups of 5 1/2 are in 15 dollars, or just dividing.

15/5.5 = 2.72 dollars

victus00 [196]

Answer:

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

PLEASE HELP WILL MARK AS BRAINLIEST!!!!! When is it a good idea to purchase discount points on a mortgage? Explain in complete s

olganol [36]

When discount points are paid, the bank collects a one-time fee at closing in exchange a lower mortgage rate to be honored for the life of the loan.

The banks consider this payment to be "prepaid mortgage interest". Meanwhile, mortgage interest is tax-deductible for eligible tax-filers so, for many mortgage borrowers, there's a tax advantage to paying discount points.

The sales of a grocery store had an average of $7,000 per day. The store introduced several advertising campaigns in order to in

Sati [7]

Answer:

a.The advertising campaigns increased the average daily sales.

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim is that the advertising campaigns increased the average daily sales.

Then, the null and alternative hypothesis are:

$H_0: \mu=7000\\\\H_a:\mu> 7000$

The significance level is 0.05.

The sample has a size n=100.

The sample mean is M=7280.

The standard deviation of the population is known and has a value of σ=1000.

We can calculate the standard error as:

$\sigma_M=\dfrac{\sigma}{\sqrt{n}}=\dfrac{1000}{\sqrt{100}}=100$

Then, we can calculate the z-statistic as:

$z=\dfrac{M-\mu}{\sigma_M}=\dfrac{7280-7000}{100}=\dfrac{280}{100}=2.8$

This test is a right-tailed test, so the P-value for this test is calculated as:

$\text{P-value}=P(z>2.8)=0.0026$

As the P-value (0.0026) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that the advertising campaigns increased the average daily sales.
